For a few days subwoofer resonated as if the volume was to the max and now it is dead. I follwed the usual troubleshootingroutine from the user manual, but the problem appears to be internal. I will appreciate any ideas of tips in order to identify the damaged component. Thanks,

Hello, To test the subwoofer when the blue light is on if you apply your thumb to the end of the subwoofer cable (the end that you would plug into the receiver) there should be feedback from the sub. If there is no feedback then the sub is not working correctly. Thanks, FJD
sub woofers are very powerful bass , with incredible sounding technology. your problem might be with the woofer wall around the circle. open the box and take the woofer out.Check if there is any tare over the corners of the cloth. sometimes there might be a crazy noise because of a little opening in the cloth caused by small tare.. if so better change it with a new 1 and make sure that the new cloth has guaranty
damaged sub woofer eg.
Thanks for rating
You need to use the LINE LEVEL connection on the pv800 (usually a rca type connector cable) and run this cable into the back of the HK 520 Subwoofer PRE-OUT connector, be sure the HK Receiver menu speaker set-up option is set to SUBWOOFER "YES"
A subwoofer is just really a mono amp for the signal. As with all amps if you touch the audio section/parts with a small screwdriver, you should hear a buzz from the speaker. (Follow the audio wires to be certain you are on the audio section). This can be used for testing the amp section. If you get no buzz or noise (anywhere) at all then it's power supply could be playing up. If you have a multimeter you can test it looking to see if it is getting power. Allways suspect any part that is on a heatsink. Before removing any suspect you can put the part numbers into Google to see if you can get them and it will give you a clue to cost.
PS don't short any parts when you touch with a screwdriver, and don't put it on the power parts.
Hello there..Thats normal only if your sub volume and the pre amp is turned up..Your amp is the cause of the speaker jump..Turn amp volume sub level down a few and check your wire from sub to amp..If all of that is good is a normal operation for pre amp warm up in sub if level is turn to max..Try unplugging amp freom sub then turn sub on stand alone(just sub outlet plugged in and no wires from base amp plugged in..If sub stops the its the amp making the problem..If it still is there then the pre amp is either dusty on inside or the outlet plug that it is plugged in doesnt have a good ground..Hope these help to solve your problem..Have a great day...
